The interviewer was trying to be mean, unfortunately. From the first minute, I knew he does not like me. His mind was totally set before the interview. It was weird because he spent 80% of the time to talk about another topic, which was not directly related to the job he was interviewing me for. He tried so bad to tell me that he knows everything and I do not. He even told me it is gonna be hard to train me. I was basically shocked by how bad his attitude was during the interview. I have changed jobs multiple times and have had many interviews in my life. This was definitely the worst interview in my life. I was just waiting for him to finish it.
